Solved 8-player Hell Baal exp

To answer your original post content, this is not a bug and never was, nor an exclusive feature of D2r and if I remember correctly you asked this once before in game and I told you it was a game mechanic and gave you the explanation behind it. The reason why this happens is that in Diablo II you have a cap on how much experience a single monster can provide and in this case, Baal reaches the experience cap with 3 players in the game, therefore if there are more than three players in that game then each individual player shall get no more than the p3 experience value. Diablo for example, reaches this experience cap at 7 players and so on. Here you can see the experience cap for various other bosses too https://www.theamazonbasin.com/wiki/index.php/Experience#Ceiling as this information has always been public.

Quote: A ceiling of 8,388,607 maximum experience from a single kill is applied at this stage, although when playing solo this is only ever reached at higher player counts for some Evils in Hell.
